When Should I Go for My First Ultrasound Scan?

when to go for your first ultrasound scan

You should get your first ultrasound scan done in your first trimester (which lasts between weeks 5 and 12). This will allow the doctor to establish your due date. Don't go too early though — your baby will only be able to be seen on the scan after six weeks of pregnancy. Accurate measurements are more easily taken around weeks 8 to 12.

What Can I Expect at the Scan?

The ultrasound scan is a common procedure that allows your doctor to get images of your baby and to check on the progress. The doctor will ask you to lie down and will apply some gel on your tummy, which will help facilitate the scan. It's also normal for your doctor to use a vaginal probe, which is inserted inside you to get a clearer look at your baby.
